I am having issues converting MIDI regions to audio files. I am using Logic Pro X and have connected the Rev2 to the interface with a USB cable. Logic is recognizing the Rev2 and I am able to write MIDI using the synth. The MIDI region plays within Logic. However, the region exports to a silent audio file. Bouncing the region in place does not work either — the bounced track shows up empty. Any help would be appreciated.
